It was odd, an almost superhumanly intellectual scientist asking for an ape's word of honor, but that did not occur to Bentley at the moment, as he nodded his head.

Barter still held his lash poised. He unfastened the leather thong which held Bentley prisoner and swung wide the door. Then he turned his back on Bentley and led the way to the door.

Bentley followed him on mighty feet and bent knuckles into the room which had first received Lee and Ellen when they had entered the cabin of the scientist.

Bentley would have gasped had he been capable of gasping at what he saw.

In a far corner, cowering down in fear at sight of Barter and his coiled whip--was the Bentley of the mirror in his stateroom aboard the _Bengal Queen_, and before that.

It was an uncanny sensation, to stand off and peer at himself thus.

Yonder was Bentley, yet _here_ was Bentley, too.

Then he noted the difference. The face of that Bentley yonder was twisted, savage. _That_ Bentley had seen Manape, and the teeth were exposed in a snarl of savage hatred. There a man ape stared at another man ape, and bared his fangs in challenge. The white hands of Bentley began to beat the white chest of Bentley--to beat the chest savagely, until the white skin was red as blood....

The Bentley buried within the mighty carca.s.s of an anthropoid ape watched and shuddered. That thing yonder was dressed only in a breech-clout, and the fair flesh was criss-crossed in scores of places with bleeding wounds left by the lash of Barter. The Apeman's brows were furrowed in concentration. The human body made ape-like movements.

Bentley knew that soon that creature, forgetting everything save that he faced a rival man ape, would charge and attempt to measure the power of Manape--fang against fang. The white form rose.

Barter caused his whiplash to crack like an explosion.

"One moment," he said. "Back, Apeman! I'll bring Miss Estabrook.

Perhaps she can placate you. She has a strange power over you both!"

Bentley would have cried out as Barter crossed to unlock Ellen's door, but he knew that he could not stop Barter, and that his cry would simply be a terrible bellow to frighten the woman he loved when she entered the room.

The door opened. White, shaken, her eyes deep wells of terror, circled with blue rings which told the effect of the horror she had experienced, Ellen Estabrook entered.

And screamed with terror as she saw the hulking figure of Manape.

Screamed with terror and rushed to the arms of the cowering thing in the corner!

CHAPTER VI

_Puppets of Barter_

The thing that Barter then contrived was destined to remain forever in the memory of Bentley as the most ghastly thing he had ever experienced. Ellen hurried into the arms of that thing in the corner.

Gropingly, protectively, the white arms encompa.s.sed her. But they were awkward, uncertain, and Bentley was minded of a female ape or monkey holding her young against her hairy bosom.

Barter turned toward Bentley and smiled. He rubbed his hands together with satisfaction.

"A success so far, my experiment," he said. "The human body still answers to primal urges, which are closely enough allied to those of our simian cousins that their outward manifestations--manual gestures, expressions in the eyes et cetera--are much the same. When the two are combined the action approximates humanness!"

That travesty yonder pressed its face against Ellen, and she drew back, her eyes wide as they met those of the white figure which held her.

"I am all right," she managed, "please don't hold me so tightly."

She tried to struggle away, but Apeman held her helpless.

"Barter," yelled Bentley, "take her away from that thing! How can you do such a horrible thing?"

At least those were the words he intended to shout, but the sound that came from his lips was the bellowing of a man ape. That other thing yonder answered his bellow, bared white teeth in a b.e.s.t.i.a.l snarl.

Barter turned to Bentley, however.

"You want me to take her away from Bentley and give her to you?"

Bentley nodded.

His bellowing attempt at speech had sent Ellen closer into the arms of Bentley's other self--henceforth to be known as Apeman. Bentley had defeated his own purpose by his bellow.

"Miss Estabrook," said Barter softly, "nothing will happen to you if you stand clear of your sweetheart...."

Nausea gripped Bentley as he heard Apeman referred to as Ellen's sweetheart, but now he remembered to refrain from attempting speech.

"But," went on Barter, "Manape has taken a violent dislike to Bentley, and may attack him if you do not stand clear. Manape likes you, you know. You probably sensed that last evening?"

Ellen visibly shuddered. She patted the shoulder of Apeman and stepped away, toward a chair which Barter thrust toward her.

She pressed her hands to her throbbing temples, visibly fighting to control herself. Her whole body was trembling as with the ague.

"Professor Barter," she said at last. "I am terribly confused, and most awfully frightened. What has happened here? What dreadful thing has so awfully changed Lee? I talk to him and he answers nothing that I understand. Is it some weird fever? At this moment I have the feeling that that brute Manape understands more perfectly than Lee, and the idea is horrible! I love Lee, Professor. See, he hears me say it, yet I cannot tell from his expression what he thinks. Does he despise me for so freely admitting my love? Has he any feeling about it at all? Has his mind completely gone?"

"Yes," said Barter, with a semblance of a smile on his lips, "his mind has completely gone. But it is only temporary, my dear. You forget that I am perhaps the world's greatest living medical man, and that I can do things no other man can do. I shall restore Lee wholly to you--when the time comes. It is not well to hasten things in cases of this kind. One never knows but that great harm may be done."

"But I can nurse him. I can care for him and love him, and help to make him well."

Barter looked away from Ellen, his eyes apparently focussed on a spot somewhere in the air between Apeman and Manape.

"Would that be satisfactory to Bentley, I wonder?" he said musingly, yet Bentley recognized it as a question addressed to him. Bentley looked at the girl, but her eyes were fixed--alight with love which was still filled with questioning--on Apeman. Bentley shook his head, and Barter laughed a little.

"You know, Miss Estabrook," he went on, "that a strange malady like that which appears to have attacked Lee Bentley should be studied carefully, in order that the observations of a savant may be given to the world so that such maladies may be effectually combatted in future. This is one reason why I do not hasten."

"But you are using a sick man as you would use a rabbit in a laboratory experiment!" she cried. "Can't you see that there are things not even you should do? Don't you understand that some things should be left entirely in the hands of G.o.d?"

"I do not concede that!" retorted Barter. "G.o.d makes terrible mistakes sometimes--as witness cretins, mongoloid idiots, criminals, and the like. I know about these things better than you do, my dear, and you must trust me."

"Oh, if I only knew what was right. Poor Lee. You lashed him so, and his body is awful with the scars. Was that necessary?"

"Insane persons are not to blame for their insanity," said Barter soothingly. "Yet sometimes they must be handled roughly to prevent them from causing loss of life, their own or others."

Now the eyes of Ellen came to rest on Manape.
